@Piel-@Mee It is the usual practice to make the rollers `preferably 'tapered .similarly tothe rollers 4 and 5, although they may be plain and not tapered where the turning can be accomplishedvon. the rollers 4 and 5. Insome. instances, lthe table may have only a portion -of the rollers tapered where the turmn can be accomplished in a limited space, as s own in Fi 12.

Re erring to Figs. 4 and 5, is vthe bloom and 4 a'1'1d1'5 are' the rollers. The rollers 4 are tapered in one direction and the rollers 5 a-re'- tapered in the opposite direction. It will'be .noticed` that the edges y, yonly rest upon the rollers. I t'will4 also be noticed that the edge'y restson 'the high portion of the rollers 5 and the edge y 4rests uponfthe high portion-of the rollers 4. Consequently, when the two sets of rollers aredriven at the same speed', and in `the same direction, then the bloom will '-be fed longitudinally in a i straight' line. according to the' direction of f so movement of the rollers, but should the direction of movement of the rollers 5 be reversed, then the bloom is turned, as the or' tions of the bloom rest between the ro ers 5,1 which are moving in one direction, while the 'portions y of the'bloom restl upon the rollers4, which are travelingiin the reverse direction,4 and, if f'this'fmo'vementis con- 'tgi'uem .the bloom is. turned continuously on t. table. Therefore,if the drivin g" mechathetwo" setsof rollers` be under the control of an loperatorz so that he can'y re. verseeither'set offroller's at'lwill, it'is`ob 'vioiisthatwhen the bloollpasses from'between the rolls of the "and ."onto the table the operator can immediately Vturn the bloom' to anyposition Adesired by .manipulating the driving mechanism of the 'rollers so thatit can be presented toiakene next pass in the proper position to befre need to the"v sha e desired..

?It' wl be seen thatY while theinvention *is .i particularly adapted 'for' handlinlblooms, .50

whieh'are being` reducedin a ro g mill, -itcanbe usedfor other -pu` oses where `it is desired to turn articles, w 'ch cannot be readily turned by'hand and which are con- 'veyed or supported vby rollerbeds ortables. j j Inthe'drawings, I have shown one method of driving them'echanism, but this arrangement 'may be modified without-departing `from the essential features of the invention.

The gear wheel 19, thloligh which the rollers 4 are driven, is driven from-*argear wheel 24 on lthe shaft 25 on which is l'nount. ed a gear wheel 26 and this gear -wheel is driven from a motor shaft 27athrotigh' a pinion 28. The aring mayhave as many.. reductions as desired.

'ia-:asin

29 is an electric motor and 30 is a'eond troller.

On the opposite side of the table is an arrangement simila'r to that described above. The wheel 23 on one of the rollers 5 is driven from a v:Wheel on the shaft 32 through an intermediate wheel Y.31. On the shaft is a gear wheel 33 which meshes with a pinion 34 on ,the 'shaft of an electric motor 6.

37 is a controller for the motor 36 which is located close to the controller 30 so that one man can manipulate both controllersf While I have illustrated a certain specific mechanism for driving each series of rollers 4 and 5, othermeans will suggest themselves and can be employed without departingfrom the spirit of the invention.

` In Fig. 6 vI have illustrated a modification .of the invention in which the rollers 4' and 5d are tapered a portion of their len h and are straight for the balance thereo This accomplishes the vsame purpose as though the rollers were tapered the full length where the width is limited and where the bloom, or other article, rests only on the tapered portion ofthe rollers.

In Fig. 7, I have illustrated another modilisation in which the rollers 4 and 5b have narrow raised Vportions 4 and 5 and the balance offeach lroller isreduced to accommo date a series ofloose sleeves less in diameter4v than theraised portion of the rolls..l B this means the bloom, or other element, wi l rest lupon'the raised portion and will be fed forofmovement of the rollers. v Fig. Q', Ih'ave illustrated a form of my ivention'in" vvvl'1 ic'l1 two tapered rollers are mounted :ong thesameflongitudinal center line. One of these rollers is at one side ofthe tablejand the other is at'the o posite side. The rollers are drivenfindepe dently and both'rollers are tapered'toward the'center-,ofthe table. V

In Fig. 9, I'have illustrated another form in which 'the' two rollers are mounted on the same shaft and each roller has an enlarged portionl some distance from the center. This enlarged rIpxortion is .preferably straight, as shown. ese two rollers are independently driven' so that they can be driven in unison or one? roller can be reversed with vrespect to the` other. 'f

In Fig. 10, I have illustrated two sets of rollers alternating with each other. The rollers'are of even diameter throughout but 'the bearings on which the rollers are mounted are slightly oif center, so that the upper bearing an le 1n respect to the other set.

' Fig. 11, one set of rollers is on a horizontal axis, while the alternate rollers are atan angle, producing the same result.

I- claim:

ward or turned according to the direction *1. The `combination ofa table, two sets ofY surface of one set of rollers is at an rollersv thereon; means for independently driving each set, the upper surface of one set being out of line with the uppersurface of the other set so that a bloom, or plate, resting on the rollers Will have a bearing at one side on one set of rollers and on the opposite side on the other set of rollers and can be moved longitudinally in either direction or turned.

2. The combination of a table; tWo sets of rollers thereon, one set of rollers alternating with the other set and one set beine` higher at one side of the center line of the table than at the other and the alternate set being higher at the opposite side of the center line than the other so that when an article is supported on the table it Will rest upon the high portions of the rollers; and means for independently driving the rollers so that when both sets of rollers are driven at the same speed and in the same direction, the article Will travel in a straight line, but when the mechanism of one set of rollers is reversed, thearticle Will be turned.

3. The combination-in a roller table or' a roller mill, of two series of rollers, the rollers of one seriesbeing increased in diameter at one side of the center of the table and the other series being increased in diameter at'.

. they can be driven in one direction in unison to feed a plate forward and can be reversed to turn a plate.

4. The combination in a 'roller table, of two sets of rollers; and means for independently driving each set,one set of rollers being tapered in one direction and the other set being tapered in the other direction so that an article supported by the rollers can be fed either straight ahead or turned, as desired. I

5. rIyhe combination in a roller table of tvvo sets of rollers, one set alternating With the other set; and means for independently driving each set, one set of rollers being tapered in one direction and the other being tapered in the opposite direction so that an article placed on the rollers can be moved in a straight line or can be turned, as desired.

6. The combination of a rolling mill; a table at one side of the mill; bearings on the table; a series of rollers mounted in the bearings; the alternate rollers being tapered in one direction and the other rollers being tapered in the other direction; With independentmeans for driving each set of rollers so that the said rollers can be driven in unison in either direction or one or the other set reversed.

In testimony whereof, I have signed my name to this specification, in the presence of t-Wo subscribing Witnesses."
